Obtaining diagnostic information in PuTTY

To obtain a log file containing diagnostic information:

Connect a computer to the gateway via USB-UART adapter.
Run the PuTTY application.
In the Load, save or delete a stored session settings block, select a previously saved connection with the gateway (for example: KISG100).
Click Load.
As a result, the previously saved values for the gateway connection settings will be loaded.
Click Open.

PuTTY will open a terminal window that displays the diagnostic information received from the gateway. The displayed information is also written to the event log file that was specified in the Log file name field when configuring the connection with the gateway.

The table below lists possible problems with PuTTY when receiving diagnostic information in Linux, and the ways to resolve these problems.
